This publication provides instructions for installing the Fiber Distributed Data Interface (FDDI) modules in an AGS+ router. These modules include the CSC-FCI or CSC-C2FCI ciscoBus interface cards and the four fiber-optic transceiver appliques, which provide single-mode and/or multimode network interfaces. The CSC-FCI operates with the CSC-CCTL ciscoBus controller card, and the CSC-C2FCI requires the second-generation CSC-CCTL2 ciscoBus controller card. The difference between the FCI and C2FCI cards is the presence of Microcode Version10.0 (or later) on the C2FCI and CCTL2 cards. Software Release 9.1 (or later) is required in order to use the C2FCI and CCTL2 cards. For specific compatibility information on upgrading the CSC-FCI card to Microcode Version10.0 or later, refer to the latest version of the publication Upgrading FDDI Cards to Microcode Version 2.1 or 10.1, Document Number 78-0857-xx (where xx is the latest version of the publication). Unless otherwise indicated, the name CSC-FCI will be used when configurations apply to both the CSC-FCI and CSC-C2FCI cards.
The following sections are included in this publication:
If you encounter a new problem and determine that it is not the result of this installation or upgrade, refer to the AGS+ Hardware Installation and Maintenance publication for initial system startup troubleshooting procedures, or to the Troubleshooting Internetworking Systems publication for additional suggestions for resolving the problem.
Following is an overview of the FDDI components.
CSC-FCI Interface Card and Appliques
The CSC-FCI FDDI ciscoBus card is the interface for both single-mode and multimode FDDI network interfaces. It is connected to the ciscoBus and Multibus backplanes in the AGS+ router. Figure 1 shows the CSC-FCI card viewed from the component side.
Figure 1 : FDDI Network Interface Card (CSC-FCI)---Component-Side View
The distance limitations for single-mode and multimode FDDI stations are listed in Table 1. Both FDDI modes provide 11 decibels (dB) of optical power.
Table 1 : FDDI Maximum Transmission Distances
| Transceiver Type | Maximum Distance Between Stations |
|---|---|
| Single-mode | Up to 6.2 mi (10 km) |
| Multimode | Up to 1.2 mi (2 km) |
The fiber-optic transceivers reside on circuit cards called appliques that provide the interface between external network connections and the internal CSC-FCI card. The four applique configurations are shown in Figures 2 through 5; each provides a unique combination of single-mode and/or multimode FDDI interfaces.
Following are the four FDDI applique mode combinations:
Both the single-mode and multimode transceivers provide a Class A dual attachment interface that can be connected to either a Class A or Class B station. Class A is a dual attachment station with primary and secondary rings; Class B is a single attachment station with only a primary ring.
The single-mode transceiver provides connectivity to single-mode FDDI fiber for distances up to 6.2 miles (10 kilometers). The connector is a simplex FC-type interface that accepts standard
8.2 to 10/125 micron (± 0.5) single-mode fiber-optic cable.
The multimode connectors are FDDI-standard physical (PMD) connectors. The connectors accept FDDI standard 62.5/125 micron multimode fiber-optic cable using the media interface cable (MIC). The MIC connector can also accept alternate cable sizes, such as 50, 85, or 100micron multimode fiber. Use care when using alternate fiber sizes, to avoid violating optical power budget restrictions.
The multimode/multimode applique also provides a DIN port for connecting an optional optical bypass switch, which allows the light signal to pass directly from the receive port to the transmit port. When this optical bypass is used, the signal is not repeated, and significant signal loss may occur when transmitting to stations at maximum distances.

Before installing any FDDI modules, ensure that your system meets the following prerequisites:
Use the show version command to verify the internal processor and software release you are running. If your current system configuration does not meet all of the above requirements, contact your customer service representative for information on hardware and software upgrades.
Follow these guidelines when working with any electrical equipment:
In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling.
Verifying the Microcode and Hardware Versions
The CSC-FCI card operates with the CSC-CCTL ciscoBus controller, and the CSC-C2FCI operates with the CSC-CCTL2 ciscoBus controller. To convert a CSC-FCI card to a CSC-C2FCI card, Microcode Version 10.0 (or later) must be installed on the card. For the CSC-C2FCI to operate with the CSC-CCTL2, Microcode Version 10.0 or later must be installed on the CSC-CCTL2 card. Use the show controller fddi command to see the current version of microcode on the CSC-FCI card. Following is partial sample output of the show controller fddi command. The microcode version is given in the first line of the output; the remaining information is not important to this verification.
List of Required Parts and Tools
Before beginning installation, verify that you received all of the parts for the interface(s) you will install. In general, each applique requires one interface card, and every two appliques require one applique card cage. If any parts are missing, contact a customer service representative.
The following parts are necessary for each interface:
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment and impair electrical circuitry. It occurs when electronic components are improperly handled and can result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:
The AGS+ card cage, shown in Figure 8, has nine slots, five of which are designated ciscoBus slots. The center ciscoBus slot is reserved for the ciscoBus controller card, leaving four ciscoBus slots available for ciscoBus interface cards.
The system uses a slot priority scheme that assigns a priority to each ciscoBus card according to the ciscoBus slot in which the card resides. The card in ciscoBus slot 0 receives the highest ciscoBus priority, while the card in ciscoBus slot 3 receives the lowest ciscoBus priority.
Figure 8 : AGS+ System Card Cage
Slot priorities are set to accommodate the amount of traffic generated by each interface card and the amount of card buffering required. Each ciscoBus interface card is placed in a specific slot with regard to other ciscoBus interface cards, if any. The order of priority is the same for both first- and second-generation ciscoBus controllers, except that the cards with the fiber-optic network interface cable FC-type connector typically used for single-mode FDDI applications with the APP-LSS, APP-LSM, and APP-LMS FDDI appliques. designation C2 can only be used with the CSC-CCTL2.
Following is a list of ciscoBus interface cards in order of priority, from highest to lowest:
Install CSC-MEC or C2MEC cards in the lowest-numbered slots, beginning with slot 0 (which has the highest priority), followed by CSC-C2CTR cards. After all CSC-MEC and CSC-C2CTR cards are installed, install CSC-HSCI and C2HSCI cards with the APP-LHS applique in the lowest-numbered available slots. Follow with the CSC-FCI and C2FCI cards. Next, install CSC-C2FCIT cards. Last, install the CSC-HSCI and C2HSCI cards with the APP-ULA (UltraNet) applique. Always install cards in the lowest-numbered slot available. For example, if you are using only CSC-C2HSCI cards (with APP-ULA), place the first in slot 0, the second in slot 1, and so forth.
Table 2 lists the maximum port and card configurations for all of the ciscoBus cards currently available. Use this table as a guide when installing new ciscoBus cards and reconfiguring your AGS+.
Table 2 : Maximum Port and Card Configurations for ciscoBus Interface Cards
Calculating the Chassis Power Budget
In an AGS+ shipped on or after October 1, 1991, the total power drawn by all installed cards must not exceed 300 watts (W) per chassis. In AGS+ chassis shipped before this date, the total power cannot exceed 260W. (The earlier chassis contained a 5 amp [A] circuit breaker, rather than the 7.5A circuit breaker used in the later chassis configuration.) Table 3 lists the power requirements for each card available for the AGS+.
Table 3 : Interface Card Power Requirements
Before installing new cards, check the power requirements of the existing system and the new card(s) to avoid exceeding the power budget. Calculate the power requirements of an existing system by adding the values for each card in the chassis; the sum is the power requirement. Determine the available power budget, subtract that sum from 300W (260W for chassis shipped before 10/1/91); the result is the power budget available for new cards.
The following example shows how to determine if you can add two new CSC-FCI cards to
Following is the procedure for accessing the chassis interior:
Figure 9 : Chassis Front and Top Panels
Following is the procedure for installing a CSC-FCI card in the AGS+ card cage. Before proceeding, ensure that your system and equipment meet the requirements listed in the section "Installation Prerequisites" on page 6.
The FDDI applique is installed in an applique card cage in the rear of the chassis; access to the rear of the chassis requires removing the front panel and top cover of the chassis.
The following procedure is only required if an FDDI applique is not already installed.
Installing the FDDI Applique in the Applique Card Cage
Following is the procedure for installing the FDDI applique in the applique card cage.
Figure 10 : FDDI Applique and Applique Card Cage---Exploded View
Installing the Applique Card Cage in the Chassis
The applique card cage can only be installed in one of the two large plate areas on the right side of the rear panel of the chassis. (For the remainder of this procedure, orient the card cage and chassis as shown in Figure 11.)
Figure 11 : Installing the FDDI Applique and Card Cage in the AGS+ Chassis
Installing a Short Ground Strap
The ground strap, which is included with all appliques, grounds the applique to the chassis to prevent EMI noise on your network interface. The applique card cage containing the FDDI appliques should already be installed in the chassis and secured with five screws. Refer to Figure 12 while you install the short ground straps.
Figure 12 : Short Ground Strap Installation
Ground straps, which are included with all appliques, ground the applique to the chassis to prevent EMI noise on your network interface. The applique card cage containing the FDDI appliques should already be installed in the chassis and secured with four screws. Refer to Figure 13 while you install the long ground straps.
Figure 13 : Long Ground Strap Installation
Connecting Internal and External FDDI Cables
The four internal ribbon cables (permanently attached to the FDDI applique) attach to the four connectors on the front edge of the CSC-FCI card. The FDDI network interface cables attach to the FDDI applique and provide the external connections to your network. Before beginning these procedures, orient the chassis with the open card cage facing you.
Connecting the Internal FDDI Ribbon Cables
The four internal ribbon cables are fixed to the applique and must be routed and attached to ports on the FCI card. The ribbon cables are labeled alphabetically depending on the number of appliques you will install. The FCI card connectors are shown in Figure 14, and the ribbon cable connectors are listed in Table 4. The ribbon cable orientation and labeling for the FDDI applique is shown in Figure 15. The ribbon cables from your FDDI applique are labeled as follows:
Connect the four applique ribbon cables to the C2FCIT card as follows.

Connecting the External Fiber-Optic Cables
Following is the procedure for connecting the external FDDI cables. Refer to Figure 6 for an illustration of the single-mode FDDI connector and to Figure 7 for illustrations of the single-mode and multimode FDDI connectors.
Table 5 : Optical Bypass Switch Pinout
After you have installed your card and applique, verify the installation by doing the following:
Two separate sets of LEDs provide status about the installation: those on the CCTL2 card and those on the FDDI applique. The LEDs on the CCTL or CCTL2 card will verify the presence (and correct installation) of the C2FCIT cards in the ciscoBus backplane, while the LEDs on the applique report. First verify the CSC-CCTL indicators, then the applique indicators. The following sections discuss the LED indicators on the CSC-CCTL and CSC-CCTL2 cards.
The CSC-FCI card contains no LEDs or indicators. The LEDs on the ciscoBus controller (CSC-CCTL) card indicate when an interface is present in a ciscoBus slot. The CCTL contains a bank of 16 LEDs: four sets of four lights, and one set for each interface slot in the ciscoBus. (See Figure 16.)
On power-up, all LEDs are on, indicating that the CCTL card is active. Once the system is booted, and the ciscoBus card microcode has completed its discovery phase, the only LEDs that are on will be those that indicate the presence of a card in any ciscoBus slot. One LED from each set of four will light an interface card is detected. (The FDDI appliques also contain status LEDs whose descriptions follow.)
The numbers above each CCTL LED indicate the ciscoBus slot number. Verify that the LED for the ciscoBus slot in which your CSC-FCI card is installed comes on and remains on. If it does not, check the CSC-FCI to ensure that it is firmly seated in the ciscoBus backplane; the ejector levers snap into place when it is installed correctly. Figure 16 illustrates which LED will light to indicate the presence of a card in the ciscoBus.
Figure 16 : CSC-CCTL Card LED Indicators---Front-Edge View
The CSC-C2FCI card contains no LEDs or indicators. The LEDs on the CCTL2 card indicate when a ciscoBus interface is present in a ciscoBus slot. The front edge of the CCTL2 card contains a bank of five LEDs as shown in Figure 17, one red LED for each interface slot in the ciscoBus, and a green (boot) LED to indicate a successful boot procedure.
One red LED will be on for each correctly connected ciscoBus card using the correct version of microcode. It will not be on if the card is incorrectly connected or if the microcode version is wrong.
On power-up, all five LEDs are on indicating that the CCTL2 card is active. Once the system is booted, and the ciscoBus controller card microcode has completed its discovery phase, the only red LEDs on will be those that indicate the presence of a card in a ciscoBus slot. The green LED is also on to indicate a successful boot operation. Figure 17 illustrates which LED will be on to indicate the presence of a card in the ciscoBus slot. The numbers above each LED (3, 2, 1, and 0 from left to right) indicate the ciscoBus slot number assigned to that LED.
Figure 17 : CSC-CCTL2 Card LED Indicators---Front Edge View
There are a series of nine LEDs located on each FDDI applique. These LEDs indicate the current line state of each of the two ports on the card. The applique LEDs are shown in Figure 18, and the line states they reflect are listed in Table 6.
Table 6 : Line State Indications for PHY-A or PHY-B LEDs
When the ring is operational (when the line protocol is up), the LEDs will oscillate between ILS, ALS, and MLS. ILS will predominate, so LED 2 will glow most brightly; LED 0 will be slightly dimmer; and LED 1 will be almost completely dark. The X3T9.5 FDDI specification explains the meaning of these line states in detail.
Figure 18 : Fiber-Optic Transceiver Applique LEDs---APP-LSS Shown
When the status LEDs show that the applique is installed correctly, use EXEC commands to verify that the new FDDI interface is properly recognized by the system. When the system is started, the interface cards query the appliques for interface information.
The EXEC command show controller fddi displays the current internal status of the CSC-FCI card(s), including the interfaces and how the card has identified them. The display lists the interfaces connected to each CSC-FCI card, and indicates that the system has identified your new interface. The display does not indicate the state of the line or protocol.
Following is a partial sample display:
To obtain more information about the interfaces, such as the state of the lines and protocol types, use the EXEC command show interface fddi to display statistics about each of the FDDI interfaces in the chassis. The first line of the show interface display names the interface and its unit address
Following is a partial sample display:
You can also use the show interface command (without variables) to display all network interfaces installed in the AGS+. Each new FDDI interface should be appended to the list of existing interfaces, with the next sequential number assigned to it. For more specific information on the available show commands, refer to the refer to the Router Products Configuration Guide and Router Products Command Reference publications.
After the FDDI module installation tests successfully, take the following steps:
This completes the installation of the FDDI card and the FDDI applique.
